Witnesses often are crucial elements in solving and prosecuting criminal or civil violations. We now regularly use data that various technologies record. Digital witness devices provide a source of largely unbiased and dependable information to the investigator and prosecutor. However, many often ignore or do not even recognize commonly available electronics as potential witness devices. One such device is the wireless router found in most homes and businesses.
As with any witness, some sort of vetting and consideration is wise. Reliability, bias, memory, physical abilities, etc., all can be factors that play roles in the use of digital witness devices and the use of their data. Whether you consider data from digital cameras, microphones, cell phones, computers, or Wi-Fi (wireless) routers, you should approach each with an open eye and determine clearly what each actually offers to your investigation. Data typically is reliable; how you interpret and present that data is key to its ultimate usefulness.
